| Abstract | Homeland security today presents a major field for technology improvement and systems development. For instance body scanners, commonly operated at airports, are basically metal detectors and therefore are not able to detect other potential hazards like ceramics or explosives as well. In this context millimeter-wave (MMW) radar systems are a promising approach, because the radiation does not present a health hazard to people under surveillance and readily passes through many optically opaque materials such as clothing fabrics. For indoor systems we propose to apply active and coherent sensors. Based on the principles of Synthetic Aperture Radar small physical apertures can be used in order to get very good resolved images providing all the image features necessary for localizing relevant objects. In order to get a view of the person from all sides either the person has to be rotated standing on a turntable or a sensor is moved on a circular path around the person. Additionally interferometric principles can be applied firstly in order to obtain a geometrically improved mapping of the reconstructed scene and secondly to reduce ambiguities related to numerical reconstruction. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
